Vermillion, can you translate the armament loadout on the Ta152 from that first chart of yours?
It almost looks as though the tested Ta had the following armament:
1 Mk 108 30mm cannon firing through the hub,
2 Mg151/20 20mm cannon mounted in the cowl
2 Mg 151/20 20mm cannon mounted in the inner wings
2 Mk 108 30mm cannon mounted in the outer wing
4 20mm cannon and 3 30mm cannon? Hmmm, can we say 'buff hunter' ?
